Radiation From Fukushima Nuclear Meltdown Found in Albacore Tuna

Radiation From Fukushima Nuclear Meltdown Found in Albacore Tuna
Trace radiation from the Fukushima nuclear meltdown disaster has been found by Oregon State University researchers in samples of albacore tuna taken off of Oregon’s coast. So far, it’s only been found in trace levels, but that is more than enough to be a cause of concern for the fishing industry there and also to consumers of seafood products.

Ever since an earthquake in Japan in 2011 triggered the Fukushima Daiichi nuclear meltdown, scientists as well as the rest of the world’s population has been worried about just how big of a disaster it really was, and how long it would take for the radiation from it to reach other countries and possibly contaminate food supplies. It appears as if these concerns were well-founded, as trace levels of Cesium-134 and 137 have been detected in albacore tuna by the OSU researchers Jason Phillips and Delvan Neville. Their research has been published in the journal Environmental Science and Technology.

Phillips and Neville chose to study the albacore tuna, as it’s a popular fish to eat and any signs that they contain radiation is an indication that perhaps other species of fish off of Oregon’s coast also contain trace amounts of radiation.

Age Matters: Older albacore tuna contained higher amounts of radiation from Fukushima

The age of the fish mattered quite a bit, at least in this particular study. While just trace amounts of radiation was found by the researchers in some of the three-year-old albacore tuna they analyzed, higher trace levels were detected in the four-year-old fish they examined. People are exposed to radiation levels every day, according to Neville, and the Cesium-134 radiation levels they found in the three-year-old albacore tuna was very small in comparison.

Neville compared the amount of radiation that a person who eats 16 pounds of albacore tuna a year at current levels to the amount a person would get from spending just “23 seconds in a stuffy basement.” For most people, 16 pounds of tuna is quite a lot of tuna, and it shows that the radiation levels that have been discovered so far are relatively safe for consumers if they don’t get too carried away with chowing down on their favorite fish of choice.

Another way to put the low risk that the radiation levels found pose is that you’d need to eat 700,000 pounds of albacore tuna, that has the highest levels yet discovered, to equal the amount that most people get exposed to merely going about their everyday existence each year.

Some sources of everyday radiation other than from Fukushima

People are exposed to more radiation than they generally realize every day from a variety of different sources. These sources include the very air we breath and the ground we walk on, as well as radon gas in buildings, cosmic rays, and x-rays.

Just from sleeping next to your spouse for 40 nights, according to Neville,is yet another source of radiation that we get exposed to “from the natural potassium-40 in their body.” The effects we experience from these sources is usually small, but the accumulative radiation a person gets who has been, for instance, exposed to dental and other x-rays for decades has been suspected of causing various types of cancer.

Though the radiation levels tripled in the samples of older albacore tuna taken before the Fukushima nuclear meltdown and after it, the trace levels of radiation discovered so far have only hit 0.1 perent of the radiation amount allowed by the FDA. Neville plans for his team to do a follow-up study involving a greater number of albacore tuna. If the amounts of trace radiation is higher in this larger sample, there might then be more of a reason to be concerned, but for now, the trace levels of radiation are relatively minor. Neville and the other researchers who took part in the study felt that the public had a right to know about even these trace levels they found in the 26 Pacific albacore tuna they analyzed.

How much radiation has the Fukushima nuclear meltdown released into the Pacific Ocean?

The amount of radiation that has been so far released by the Fukushima nuclear meltdown is staggering. It’s been estimated that roughly 70 trillion bacquerals of radioactive material has made its way into the Pacific Ocean because of the meltdown. A bacqueral is a unit that measures radioactivity.

The radiation from the Fukushima nuclear meltdown that scientists predicted in March would hit the West Coast of America by April has arrived, more or less on schedule. According to the same scientists, the radiation levels wouldn’t be high enough to pose much of a health or environmental concern. The latest study by the OSU researchers points to the increase in the levels of radiation found in albacore tuna due to the Fukushima nuclear meltdown, but it is in agreement with the scientists who predicted that the radiation levels would not pose much of a danger to humans or the environment.

    Good post and right to the point. I don’t know if this is really the best place to ask but do you folks have any thoughts on where to hire some professional writers? Thanks in advance

    I got this website from my friend who told me regarding this web site annd now this time I am visiting this web siteaand reading very informative articles or reviews here.

    This currently is not the full picture. Unlike previously predicted, the “fallout” from the three melted cores in Fukushima (“hot particles”) that would normally be ejected near ground level and thus deposited close to source, seem to have resurfaced not only in Tokyo but even in the Americas and Europe. Not only does this point to much more violent explosions (hydrogen/oxygen etc.) “back then” but it remains a mystery that this has not been detected earlier. It’s either a cover-up or no one bothered looking earlier.

    I suppose the radiation they found had “Fukushima” tags?

    How did they conclude the radiation found in tuna along Oregon coast had come from Fukushima? If they are scientists, they do or should know that all the fish of entire world carry radiation in the natural environment, so do we human beings.

    The sea currents are very different to that of a river. Give a gentle one-direction-stir in the water of a bath tub and wait until the movement is transferred to the whole tub. Then put a drop of ink in one end. Now trace the ink in the other end after 30 minutes. Good luck.

    The video shows “A Time-Lapse Map of Every Nuclear Explosion Since 1945”. If you don’t have time, slide up to 12:00 to see the data by country or 13:40 for the final state as whole (1945 – 1998).

    The only bright side is it’s not radiation is not in high enough concentrations. But, I’ll be staying away from Tuna for a while.

    As time goes by and TEPCO the Japanese power company continues to dump millions and millions of gallons of radiation into the Pacific Ocean as they have been, the problem will grow worse causing the fish and seafood in the Pacific ocean to become more contaminated with toxic radiation that will cause health damage to those that eat it! Anyone eating Pacific Ocean fish and seafood should strongly consider doing a radiation detox with the mineral called Zeolite that has been proven to safely remove both radiation and heavy metals from the body! For more information on this wonderful detox mineral do a search for the single word Zeolite.
